Light pinpoints stress and strain – A Brillouin’t idea from OZ Optics
Remote Pipeline, Perimeter, and Structural Monitoring…
Foresight™, from OZ Optics, is a sophisticated Distributed Strain and Temperature Sensor (DSTS) based on Brillouin scattering in an optical fibre. It can measure subtle changes in both temperature and strain along the length of the fibre over time, or the rapid location detection of a major disturbance within a second.
By wrapping or embedding a fibre inside a structure, such as an oil pipeline or dam, detection of the structure being strained or heated/cooled is possible, allowing for pre-emptive maintenance. Such monitoring capability is invaluable in critical structures where cracks and failure could involve loss of life or other unprecedented costs.
Foresight™ can also detect and report larger signals within one second with only a slight loss of accuracy. This sort of response speed is ideal for security applications or strains caused by earthquakes where an immediate measurement and reaction may be required.

OZ Optics introduces new Variable Bandwidth Tunable Filter
OZ Optics has introduced a new tunable filter that has the ability to tune both the centre wavelength and the transmission bandwidth.
Two independently adjustable thin-film filters allow the setting of the lower and upper edges of the pass-band region. With this method, the pass-band can be tuned from 1 to 18 nm FWHM and the centre wavelength shifted by over 40 nm.
The transmission band features a flat-top profile, providing uniformly low losses and low PDL across the pass-band region, and high rejection ratios outside the pass-band. Devices can be custom made for wavelength regions of interest and can use either singlemode or polarisation maintaining fibres.
Two manual controllers to set the upper and lower pass-band regions, with an electrically controlled model due later this year. Applications include WDM testing, spectral filtering, spectral imaging or microscopy, and others.
For more information, please contact us.
Non-contact Visible Fault Location in fibre added to OZ Optics range
OZ Optics has expanded its range of Visible Fibre Optic Fault Locators with the addition of a benchtop non-contact tester, the ideal solution for inspecting devices with no connectors on the fibre ends. Visible Fibre Optic Fault Locators launch either 520 or 635 nm laser diode light into a fibre to enable discovery of breaks or sharp bends, which are revealed by the resulting scattered light emerging from the sides of the cable.
Fault locators are now available in four models: two benchtop and two portable…
- Benchtop Non-Contact, for CW and pulsed operation
- Benchtop CW High Power only
- Portable pen – CW only
- ‘Pocket size’ offering CW or pulsed output
Pulse modulation aids in locating faults under high ambient light conditions and improves battery life. 2 Hz modulation is easy to detect with the naked eye, while 270 Hz and 2 kHz pulse modulation modes are used for fibre identification by detectors.

New electronic Polarisation Controller/Scrambler from OZ Optics
OZ Optics now offers a high speed electrically operated Polarisation Controller (EPC) that provides continuous polarisation control with negligible insertion and return losses in a compact, easy to operate package. Four birefringence transducers, each controlled by an analogue input signal, modify the polarisation in orthogonal directions. The device can be operated from 1260 to over 1650 nm (custom wavelengths available) with the response speed of each transducer surpassing 30 kHz.
Applications include polarisation controllers for optical networks, Polarisation Dependent Loss (PDL) control, Polarisation Mode Dispersion (PMD) compensation modules, and polarisation scramblers for polarisation parameter characterisation systems. The redundant transducer design allows continuous control of polarisation without having to ‘reset’ voltages.
High Speed Polarisation Controllers are offered as base modules requiring external electrical signals to operate, OEM modules with driver electronics and control interface, or stand-alone benchtop test instruments. For more information, please contact us.

OZPEN – A carbon dioxide cleaning system for optical components
The OZPEN – from leading fibre specialist OZ Optics – is a versatile small surface area precision cleaning system for fibre optics and other components. The OZPEN produces an adjustable spray of clean dry air or nitrogen containing small carbon dioxide ‘dry ice’ particles to efficiently remove foreign matter from a surface.
The composite spray cleaning technique is a patented process using the chemically active, dry CO2 spray for efficient and effective removal of inorganic and organic surface contamination from substrate surfaces.
The cleaning unit delivers a precisely controlled accelerated stream of solid carbon dioxide particles at high velocity. This snow is created from the conversion of liquid CO2 to solid CO2 particles and CO2 gas at the spray nozzle. The nozzle, propellant pressure, and temperature are adjusted for optimal cleaning process.
Thin film organic contamination can also be removed by snow cleaning providing it is soluble in liquid CO2. Typical light oils are good candidates for CO2 cleaning.
As the solid CO2 spray within the plume is at a temperature of around -78 °C, the cooling properties of can be used to remove contaminants with high water content, first by freezing, then by fracturing it from the underlying substrate.
For more information on the product and its uses, please contact Elliot Scientific or see the video here.
